We have a Roku Premiere model 4620X which has been a problem for 6 months now. It constantly reboots, and when it does start it has massive screen issues which sometimes require an additional reboot. Sometimes we can just use the hotkeys to go to another app and then go back to home to resolve it.
Once the device is on and the screen issues resolved, we do not have issues with any specific channels. All issues are with starting and screen resolution on start.
I cannot find any reference to these issues elsewhere. Do we have a lemon? Is there a solve for this?
